I shall preferably describe my invention as applied to wrappingconically shaped units, such as for instance, medicated cocoa buttercones.

Referring to the illustrations, which show a preferable embodiment of myinvention:

A cast iron stand is provided having suit able supporting legs andplatform 26. The entire machine is driven by a single motor 2'? which issupported on cross supports 28 extending between the rods 29. The maindrive shaft 30 carries a. gear 31 which is driven by the pinion 32 onshaft 33, which shaft is operably connected to the motor pinion 27 andgear 34 mounted on the end of the shaft A suitable clutch 35 may beobviously provided for disengaging the mechanism from the constantlyoperating motor 27.- iii The wrapping paper 37 is preferablv mounted onthe spool 36 and is passed under a tightening roller 38 supported on thearm 39 which is pivotably mounted at 39 The arm has a depending bracket39 which limits the downward movement of the tightening roller 38. i

The paper 5 passes over the corner roll 40 and between a pair of feedrolls ll and 42 which are respectively rigidly mounted to the shafts 43and 4:4. The shafts 4:3 and 4% and the roll 4:0 are supported in thebrackets 45 mounted on the platform 26.

A pair of like gears 46 mounted on the end of shafts L3 and 44- are inmesh and Bil lit)

lUO

thereto and which ratchet wheel imparts an intermittent rotary motion tothe shaft lland feed rolls all and l through the meshed g 146. Thisintermittent rotary n'iotion imparted to the ratchet wheels 4? by meansof a pawl l8 which is pivotaliy mounted to the arm a9.

The arm 49 is cast integrally with the pinion 50 which is looselymounted on the shaft. leiadjzurently to the ratchet l7. The pawl 46 hasconnection with a small coil spring 51 which extends from it to the arml9 and which maintains the pawl under resilient pressure in engagementwith the ratchet wheel :7.

The pinion 50 and its integral arm l9 receive an oscillating movementthrough the rack 52 which is slidably mounted in the housing to maintainits constant connec-' tion with the pinion 50. The lower end of the rack52 is extended for pivotal connection to the crank disk 54. The crankdisk 5-4: is fixed on the end of shaft 55 which is supported in bearings56 and which is driven by a pair of bevel gears 57 operatively connectedwith the main drive shaft 30.

The upper roll shaft 43 is carried in vertically adjustable bearings 43screwmounted in the tops of the brackets l5.

After the paper strip is intermittently fed from the rolls 41 and 42 itis engaged by the forming rolls 58 and 59. The upper roll 58 ispivotally mounted on the bracket 60 and bears down with its convexperiphery into the grooved periphery of the roll 59 and so imparts aninitial concave formation to the strip of wrapping paper as it isintermittently fed therebetween. The shaft 59 carries a rigidly fixedsprocket 61 which is driven by the chain 62 extending from the drivesprocket 63 which is fixed to the shaft 44. On the other end of theshaft 59 is a fixed gear having engagement with a like gear on the shaft58 whereby the two rolls 58 and 59 have a uniform coaction.

The casting 6a which supports the rolls 58 and 59 is supported on thesupporting bracket 65 and contains a passage G L of gradually decreasingdiameter into which the arcuately bent strip of paper is fed from therolls 58 and 59. The casting 64: is provided at its outer end with anenlarged perpendicularly extending integral block 64 which is providedwith vertical grooves 64 forming guides for the shear blocks 66 to whichare secured the shear blades 67. The function of the shear blades 67 isto sever the paper strip at even lengths upon its passage from theforming passage 6%.

The shear blocks 66 reciprocate in opposite directions and are actuatedfrom the main drive shaft 3 by means of a cam drive which is illustratedin Figs. 13 and 14- and which employed as a standard for the other unitshereinafter specified. This cam drive also shown in Fig. ltogether withthe interconnecting links and cranks for actualing the shear blocks.Referring now in Figs. 41-, 9, 13, and ll, the link 65: is pirotallyconnected at its upper end to a crank arm 69 which is mounted in thebracket To. at its lower end the link is provided with a slot 68 topermit the passage of the main drive shaft 30 therethrough. This slottedend is mounted adjacent and between the cam T1 and collar 72. A rolleris liiOl'li'l'ted on the link 68 for engagement by the cam T1 wherebythe link 68 is reeiproeated to move the end 69 of the crank 69 upwardhfrom the position shown in Fig. at. A spring 74 is provided to actagainst the cam movement and to thereby always maintain the cam 71 inengagement with the roller '72").

Referring now particularly to Figs. and 9, the upper shear block 66 isPlVOtZlllj." mounted to a crank arm 75 (similar to arm 69) which ispivoted at (5 to the block til" and the depending portion of the arm T5is connected with a link 76 to the end 69" of the arm 69. The lowershear block (36 is provided with a pin T? which extends into a slottedopening 7'? within the link 76. it is now obvious that in the upwardmovement of the links 68 and 76, the lower shear block 66 will moveupwardly while the upper shear block will move simultaneousl downwardlydue to its mounting on the crank arm 75, and in such movement. theconically formed strip of extending paper will be sheared by the blades67 and sheared conical wrapper indicated by '78 which extended into theretaining member 79 will now be ready to be moved in the rotary c isl:carrier 80 into loading or changing position.

The rotary disk carrier 80 is provided with six wrapper retainingmembers 7 9 which resemble a bolt, having av head Til and a nut 79 theinterior of which is here provided with a conical bore 79.

The intermittent operation or rotation of the disk carrier 80 will laterbe more fully described.

Preliminary to loading or charging of the wrappers the carrier 80 movesone sixth of a rotation in a clockwise direction shown by arrow in Fig.l, and thus brings the wrapper 78 from the shearing position intoalignment with the rotary shape-forming plunger 81. (Shown enlarged inFig. 8.) This plunger revolves at a constant relative high speed, andbetween the next movement of the carrier 80 moves quickly into and outof the aligned wrapper 78, thus definitely setting the conical formationof the wrapper. The plunger 81 is slidably mounted in the bearing macaw82 and is slidably keyed to a revolving end carrying the pulley 83 whichpulley is constantly driven by a belt, 841 passing over a pair of idlersheaves 85 from the drive pulley 86 which is fixed to the main driveshaft 30. As the plunger 81 is slidable longitudinally within its keyedconnection 87 it can readily be quickly moved or reciprocated by a cam71 on shaft operating the link 68 (see Fig. 3, similar in constructionto link 68 shown in Figs. 13 and 141 and described above) which link 68operates the arm 117 pivoted at 118 to reciprocate the connection 87through the link connection 119 (see Fig 1).

The next one-sixth rotation of the carrier 80 will bring the wrapper 7 8into alignment with the loading chamber shown also in Fig. 8, but beforedescribing this structure I will proceed with the specifications of myimproved feeder.

The feeder is illustrated in Figs. 1, 2 4, 5, 6, and 7 and comprises acylindrical receiving chamber 88, open at the top to receive a quantityof the medicated cones. A right angular discharge opening 88 is providedin the bottom 88 and portion of the side, as shown in Figs. 5 and 6.Laid on the bottom 88 and within the chamber is an intermittentlyrotating disk 89 which is fixed to a central shaft 90. The periphery ofthe disk 89 is provided with equally spaced openings 89 and the portionbetween the openings is slightly beveled towards the edge of the disk.The length of these openings 89 being slightly greater than the lengthof the cones. The shaft 90 extends through the bottom 88 and carries afixed bevel gear .91 which meshes with the bevel gear 92 which is fixedto the shaft 93 the other end of which carries the ratchet 9 1, whichratchetis intermittently operated by the spring-pressed pawl 95 pivotedon the lever 96 which is also pivotally mounted on shaft 93. The shaft93 is carried in the bracket bearing 93*. The lever 96 is oscillated bythe connected rod 97 which is fixed to the crank disk 98. The crank disk98 is fixed to the shaft 99. The shaft 99 is carried on the bracketbearings 100 and is driven by a )ulley 103 fixed on the main drive shaft30.

As the disk 89 rotates clockwise in Fig. 6, the quantity of cones willbe moved upwardly in the inclined hopper toward the opening 88 and tothin or reduce this quantity to a layer whereby the openings 89 willeach receive a single cone for conveyance to the discliarge opening 88*,I provide a pair of rotating brushes 1041 mounted on the arm 105 whichis keyed to the shaft 106. On the upper end of shaft 106 a gear 107fixed thereto meshes with gear 108 which is fixed to the shaft 90 forthe purpose of receiving intermittent motion. "IlZ'Wll-lbe noted'thatthe chamber 88 is inclinedly and pivotally mounted at 88 to thesupporting bracket 109. i

For the purpose of controlling the discharge of only whole or perfectcones to the feeder tube 110 I provide an intermittently rotating drum111 which comprises a pair. of flanges 111 between which is acylindrical hollow sleeve 111 having four equally spaced depressions 111to receive the unit cones. The depressions 111 extend longitudinally ofthe cylindrical sleeve 111 and are provided with relatively largeopenings or slots 111 extending longitudinally for, the greater part ofthe depression. It is now apparent that if a part of a cone is passed tothe drum 111, such part if shorter, than the length of the opening 111will fall through the sleeve lll finto the imperfect cone tube 112 fordischarge into any suitable separate container which may be placedalongside of. the machine.

As a further means of.avoiding the passage of any imperfect cone or partof one. 1 provide the feeder tube 110 with a wire frame body 110 andjust opposite the tube 113, which also discharges into the samecontainer for the tube 112, I crimp or deform one of the lower wires asat 110 which will afford a means of by-passing the small broken parts tothe tube 113. The drum 111 is supported on a shaft 111 extendingintegrally with and in opposite directions from both flanges 111 intobearings 1 1-4, and at one end of this shaft I secure drive disk 115having a. plurality of equally spaced pins 116 which extend outwardlyinto the path of the pivoted end 96 of, the lever 96. The end 96 isprovided withan integral extension or lug 96. which normally engages theunderside of the lever 96 to afford an upward movement of the end 96'rigidly with arm 96. Referring now to Fig. 4-, if. the disk 98 is movedanticlockwise, as the lever 96 will be oscillated to move the pivotedend. 96 upwardly and rigidly with arm 96 during its engagement of one ofthe pins 116 to rotate the drum 111 anticlockwise. In the reverseoscillation of the lever 96, the end 96 will be moved downwardly, butbecause of its pivotal support on arm 93. will be swung past the pin11.6 which it had previously raised and will after passing same drop byits weight into normal operative position under the next pin 116 into aposition to move such pin upwardly on the next upward oscillation of theend 96 It is necessary that each one be dropped into the wire tube withthe larger or heavier end of the cone forward and for this pur- 1 pose Iprovide depressions 111 at end of the depressions 111 whichdepressions'lllare arcuate cavities, smaller in diameter than the baseof the cone but greater than its apex Thus the apex of each cone. will 1lodge in same and in the discharge of the cones from the drum 111, thebase of the cone will roll out first with the apex lying in the cavity111 and will be retarded in its rolling discharge. This arrangementinsures the. base of the cone rolling or discharging first.

The lower end of the feeder tube 110 is provided with a feeder chamber120 comprising a cylinder chamber open at the front or discharge side at120. The chamber 120 is fixed to the bracket with a bolt 121, (see Fig.8). The bearing 122 is also cast integral with the bracket 65 andcarries the slidable feeder plunger which is rigidly fixed to theoperating sleeve having an integral flange 12%. The feeder plunger endis slightly beveled at its upper side 123 and carries a rubber tip 12 1.

The cones slide down the tube 110 to the stop pin 125 which normallyextends into the upper part of the feeder chamber to support thelowermost cone. The pin 125 is lined to a depending member 126 which isrigid on the pin 127. The pin 127 is mounted for reciprocation in theupright supports 12S rigidly mounted on hearing 122. A coiled spring 129extending between the collar 127 and upright 128 retains the pin 127 ina position with the stop pin extending into the interior of the feederchamher 120 to support the cones in the tube. The outer end of pin 127is provided with a forked end 127 having a slotted opening 127 for thepin 130 which is carried in the upper end of the lever 131 pivotablymounted to the upright 128 at 131 hen the feeder plunger 123 moves intoloading position as shown by the full lines in Fig. 8, the cone lying inthe arcuate extension 122 is pushed into the aligned wrapper 78 whichwas brought into such position by the one-sixth rotation of the carrier80, from its preceding aligned position with the form setting rotaryplunger 81 and during the loading movement of the feeder plunger 123,the flange 12st engages the notched end of the lever 131 thus moving thepin 127 outwardly against the pressure of the coil spring 129 to quicklywithdraw the stop 125 to allow another cone to pass down into theloading chamber. The pivotal mounting of the lever 131 is so arrangedthat the release of cone from the tube 110 is done very quickly andbefore the next cone would also pass down the pin 125, due to the actionof the spring 129, is quickly passed into a stop position to retain it,thus only one cone is fed at each reciprocation of the pin 127. The conedischarged into the feeder chamber 120 is seated in a slightly inclinedposition with its base on the inclined face 123 of the feeder plunger123 and in the reverse or outward movement of the plunger 123 is laidinto the extension 122 into a proper loading position with its apexforward ready to enter the conical Wrapper on the next loading movementof the plunger 123.

To lay the cone down on its side in the extension 122 I provide a rubberlip which is fixed to the extension 122 by screws 133 and in suchposition that the cone resting in an inclined position on the bevel 123will be easily tilted off its support.

The operation of the plunger 123 and its coasting mechanism isaccomplished through a cam 71 on shaft 55, operating the link 68(similar to 6S) arm 13 1 which is pivoted at 135, and the short link 13Gconnecting the upper end of arm 13-1: with the sleeve 124.

After the cone is loaded into the wrapper, the carrier 80 makes anotherone-sixth revolution and the loaded wrapper is brought into alignedposition with the end folding and sealing reciprocating plunger 137which is supported in the bearing 13.

The outer end of the plunger 137 carries a rigidly mounted sleeve 139which is recipro rated by the standard mechanism comprising cam 71,mounted on shaft 1-11-0 which is driven by a pair of bevel gears 141from the main drive shaft 30 si'qiported by brackets The cam 71 drivesthe link (i8 (similar to (38) which link is connected to the pivoted arm1 12. the upper end of which is connected by the link 1 13 to the sleeve139.

The inner end of the plunger 137 carries a nut 137 on the end of theintcg 'al section 137 which is of small diameter and a slidably mountedcylindrical head 1 14 which is formei'l vith a central conicaldepression 1 hr adapted to lit over the head of the retaining member 79.It may here be stated that the mouth of the depression 14A: wider thanthe open end of the projecting wrapper, so that the wrapper is gatheredtogether as the mouth of the depression lll engages same. Normally thespring 14-5 retains the head 14-iproiecting beyond the nut 137 so thatas the plunger 137 is moved forward the conical dc iiression will be thefirst to engage the open end of the wrapper. The tension or resistanceof the spring 145 is suthcient to fold the wrapper into the de pression1 1 i while upon continued movement of the plunger the 1 end 137 willengage the folded end of the wrapper to permanently fix or seal same.

The next one-sixth rotation of the carrier 80 will bring the loadedwrapper with one end sealed into alignment with the apex sealingmechanism illustrated in Fig. 10. The apes sealing mechanism consists ofan oscillating spindle 1 1-6 supported in a bearing 147 and having aratchet wheel 148 at its outer end. The ratchet 143 is operated by arack 149 having pivotal connected with the rotary disk 150 mounted onone end of the shaft 151, the other of which is driven by a pair ofgears 152 from the main shaft 30. On the inner end of the spindle 146, Imount a pair of coacting fingers 153 which are pivotally mounted at 153*to the parallel side supporting bars 15a which are rigid with thespindle. The ends of the fingers are disposed toward each other as at153? to provide means for gripping the projecting apex of the wrapper.To maintain the tin ger in separated or open position as shown dotted, Iprovide leaf springs 155 riveted at one end to the spindle and havingtheir free ends exerting pressure against the fun gers. A clutch 156loosely mounted on the spindle and having a conical end 156 is arrangedto slidably engage the beveled ends 153 to bring the finger ends 158together against the pressure of the leaf springs 155. The operation ofthe clutch 156 is accomplished by the lever 157 which is pivoted at 158and the lower end of which is reciprocated by the standard cam mechanismcomprising cam 71 actuating the link 68. It is now apparent that as therack 1 19 oscillates the spindle 1 16, the fingers 153 aresimultaneously brought into engagement with the projecting apex of thewrapper whereby the wrappers apex is sealed by a twist.

The loaded wrapper now being sealed at both ends is ready to bedischarged from its retaining member 79 within the carrier 80.

The discharging mechanism is also illus trated in enlarged detail inFig. 10 and com prises a plunger 159 having a discharge end 159 and asupporting bearing 160. A sleeve 161 rigidly fixed to the plunger 159 isconnected by the link 162 with the operating lever 163 which ispivotally mounted at 164 and actuated by my standard cam mechanismcomprising cam 71 and link 68.

The final. operation to be described is the actuation of the carrier 80in its intermittent motion which as above stated was one-sixth of itscomplete rotation. The mechanism comprises a ratchet wheel 165 which iskeyed to the shaft 166 upon which the carrier 80 is fixedly mounted.Adjacent this ratchet wheel 165, and loosely mounted on the shaft 166, Iprovide an oscillating arm 167 to which I pivot a spring-pressed pawl168, which pawl constantly engages the ratchet wheel 165 and upon eachoscillation of the arm 167 move the ratchet wheel one-sixth of itscomplete rotation, thus imparting an intermittent motion to the shaft166 and carrier 80. The oscillation of the arm 167 is attained by theconnecting rod 169 which connects its end with the crank disk 170mounted rigidly to the end of the main drive shaft 30.

Referring to Figs. 11 and 12, the integral vertically extending block 6&of the rolls supporting casting 64: has attached thereto by screws 170 ametal plate 170 which extends outwardly toward the carrier 80 and whichhas the outer end thereof bent at a right angle and provided withsaw-like teeth 170 which are adapted to engage and extract the wrapper78 which for some reason should not be filled during the operation ofthe machine; in such instance, for example, as when the feeder shouldmiss depositing a charge.
